(Presented by TLPBLACK: High-fidelity threat intelligence and research tools for modern security teams. From curated Passive DNS and real-time C2 monitoring to actionable IOC feeds and daily malware samples, we help defenders detect, hunt, and disrupt threats faster, with seamless integration into SIEM and SOAR workflows.) Three Buddy Problem - Episode 91: This week we dig into Google's new cyber threat disruption unit announced at RSAC, Kaspersky confirming Coruna is a direct evolution of Operation Triangulation, and a cascading supply chain compromise that chained through LiteLLM, Trivy, and Checkmarx into thousands of software pipelines. Plus, VCs and the breathless AI hype, Apple's iOS 26.4 and silent patches, the FCC's ban on foreign-made routers, and Symantec catching an APT looking for Chinese military data.

The greatest APT hunter of all time, Apple's exploit kit problem, Microsoft FedRAMP mess

Attackers tip their hand by touching ’em giving you the one alert, when it matters. With zero admin overhead and almost no false-positives, Canaries are deployed (and loved) on all 7 continents.) Three Buddy Problem - Episode 90: We remember GReAT teammate Sergey Mineev, the legendary malware hunter behind discoveries like Equation Group and Project Sauron (Remsec), including stories about his methods and why he was the best to ever do it. Plus, another in-the-wild iOS exploit kit discovery and a long overdue conversation about Apple's responsibility to hundreds of millions of users on older iOS versions; the ProPublica Microsoft/FedRAMP bombshell, Interlock ransomware sitting on a Cisco zero-day, the White House AI policy framework, and Supermicro co-founder $2.5 billion AI chip smuggling bust.

From curated Passive DNS and real-time C2 monitoring to actionable IOC feeds and daily malware samples, we help defenders detect, hunt, and disrupt threats faster, with seamless integration into SIEM and SOAR workflows.) Three Buddy Problem - Episode 89: We discuss Iran hacktivist group 'Handala' wiper attacks against US medical device maker Stryker, Microsoft Intune MDM tool abuse, and whether Iran's cyber retaliation is as scary as the headlines suggest. Plus, ESET's discovery that Russia's APT28 original implant developers are back after years of silence, Dutch intelligence warnings on Russian campaigns targeting Signal and WhatsApp accounts, Apple finally patching Coruna exploit kit vulnerabilities for older iPhones, and Google sharing Coruna samples that raise new questions about the exploit kit's proliferation chain.

Trenchant, Peter Williams, and the proliferation of a Shadow Brokers-level iOS exploit framework

Three Buddy Problem - Episode 88: We unpack the fallout from public documentation of the Coruna iOS exploit kit, the likely connection to the Peter Williams/Trenchant exploit sale to Russians, how it slipped from government hands into criminal use, and the widening use of zero-days by surveillance vendors and cybercriminals. Plus, fresh signs of cyber-warfare activity tied to Iran and Israel, the FBI’s disclosure of a breach affecting internal surveillance systems, and the latest debate over AI, security tooling, and Anthropic’s public stumbles.

Matthias Frielingsdorf on the mysterious Coruna iOS exploit kit discovery

(Presented by TLPBLACK: High-fidelity threat intelligence and research tools for modern security teams. From curated Passive DNS and real-time C2 monitoring to actionable IOC feeds and daily malware samples, we help defenders detect, hunt, and disrupt threats faster, with seamless integration into SIEM and SOAR workflows.) Matthias Frielingsdorf (co-founder and VP of Research at iVerify) joins the show to discuss the mysterious US government connection to 'Coruna', an iOS exploit kit fitted with 23 exploits across five full chains targeting iPhones iOS 13 through 17.2.1. We talk about a "gut feeling" connecting this to the L3 Trenchant/Peter Williams exploit sale scandal, how a nation-state-grade exploit kit ended up in the hands of a Chinese cybercrime group chasing crypto wallets, and what it means that criminal organizations are now deploying iPhone zero-days at scale. Matthias walks through what iVerify can and can't do on Apple's locked-down platform, why he thinks Apple needs to give defenders more access, the Lockdown Mode debate, the thorny issue of sample sharing in the research community, and practical advice for everyday iPhone users facing a threat landscape that just got a lot more complicated.Links:Coruna: The Mysterious Journey of a Powerful iOS Exploit KitiVerify Details First Known Mass iOS AttackCoruna: Inside the Nation-State-Grade iOS Exploit Kit (iVerify)Wired: A Possible US Government iPhone-Hacking Toolkit Is Now in the Hands of Foreign Spies and CriminalsLockdown Mode or Nothing Zero-day reality check: iOS exploitation About Lockdown Mode (Apple)Charlie Miller on hacking iPhones, MacbooksTLPBLACK
